For sure! You can also restart your system and the memory will be reclaimed :-) The good news is that gnome developers are on the issue and even found the cause - as expected, it is a matter of incomplete cleanup of “garbage”. Probably this will be fixed quite soon in 3.28 at least.

Good to hear it might not be a gnome issue after all. On Ubuntu, the memory leak is real. Right on login, memory usage of gnome-shell typically is about 170, quickly grows to 350 after a few minutes, and then steadily grows over several hours to 800 - 900 after four or five hours, never to go down substantially. This will however usually not be noticed on average use, and if the system is shutdown daily.

.local/share/applications is an equally good place to put your desktop file. That only affects your current user configuration, and doesn´t require you to have root permissions and change system folders.

Gnome since version 3.26 has a “Shutdown” command build into the shell, but unfortunatelly, this is not a regular desktop file and you cannot pin it to your favourites (or Dash if you use Dash to dock). To achieve that, you need a desktop file:

This series of commands automatically will create a shutdown.desktop file in your local applications folder. In the dash, you now will have two icons appear when you look for shutdown. You will be able to right-click the instance coming from the desktop file and select “Add to favorites”.

This was a clean install of Antergos. I used the tarbal from citrix. I probably had to install some dependencies as indicated from error messages of the install script, but unfortunately, I did not take note of that. Installing from AUR indeed should automatically pull in the required dependencies.

If Unity 8 does not run in a stable way on its home distribution, then I doubt whether it will easily be installed on Antergos, and if it can, if it will run well. Not sure about the current status of Unity 8, and whether a group effectively is continuing its development.

If you do not want to switch the shell theme, then the theme will need to be fixed. With some research, you may be able to fix it yourself. Alternatively (and better as it will benefit all users), you should file a bug to the theme developers (unless you are able to upload a patch yourself).

It would be good to start “top” in the terminal at a time where your fans keep spinning, to see what process might be eating your CPU. It is not clear what desktop you are using, but if it is the gnome or deepin desktop, then the culprit might be tracker that is indexing your files. The specifications of your hardware are also not clear, but if these are to the lower end, the activities of tracker would be very noticeable.

Another option: move to libinput. After this, you will see some more configuration options in the gnome settings, including natural scrolling and two-finger scrolling.

To switch to libinput, uninstall xf86-input-synaptics. Make sure libinput and xf86-input-libinput are installed (I think they are installed by default in Antergos, but synaptics is in charge if xf86-input-synaptics is also installed)
